	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  If there is no creation time of a collection, we just add an empty

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Performance improvement: there is no need to fetch the user that we want
	  to delete from database before deleting it. Now, we just call the
	  deleteUser() method of the UserFactory with the identifier of the user.

2011-03-03  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:

	  New. Abstract class that should be used as the base class for the
	  artifact and collection out resource. The most stuff to handle the

	  correct methods in the artifact database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionOutResource.java:
	  New. The OUT Resource for collections. It implements the two abstract

	  artifacts)

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java: Added a
	  'cleanup(Object context)' method to the interface definition of artifacts.
	  This method should be called before exporting an artifact and should
	  remove data stored on an artifact (or its current state) which have been
	  written by an 'out'.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	  Default implementation of cleanup method - nothing is done here yet.
	  Override this method if an artifact needs to be cleaned before an export.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java:
	  Call cleanup method on the proxied artifact if proxied is existing.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Call cleanup method before exporting an artifact as xml.

2010-03-19  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  artifact a new identifier.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Set a new identifier on an artifact after deserializing it.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java:
	  Set the identifier of the proxied artifact right after setting its own
	  identifier.

2010-03-19  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  Issue208 (Artifact import)

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ImportResource.java:
	  New server resource to import an artifact from an incoming xml document.
	  The resource is available as /import and accepts xml documents send via
	  HTTP POST.

	* artifact-database/src/main/resources/sql/org-postgresql-driver.properties,
	  artifact-database/src/main/resources/sql/org-h2-driver.properties: New sql
	  statements to update an existing artifact.

2010-03-16  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  Issue208 (Artifact export)

	* artifact-database/doc/example-conf/conf.xml: Added a section to configure
	  a secret string used to identify artifact imports for security reason.
	  Incoming artifact imports need to be identified with this secret, otherwise
	  the import should be blocked.
	  Xpath for this secret: '/artifact-database/export-secret/text()'

	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:

	  Added some methods for exporting artifacts as xml documents. The data part
	  is base64 encoded. A secret key is used while encoding this data to verify
	  artifact imports, later.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Added an artifact loader interface used to deserialize artifacts. 
	  getArtifact() implements such an ArtifactLoader to return
	  PersistentArtifacts.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ExportResource.java:
	  New. ServerResource to export artifacts (innerGet). This resource is
	  available under "/export/{uuid}" via HTTP-GET request and returns an
	  artifact specified by uuid as xml document.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/RestApp.java:
	  Register ExportResource to webserver.

2010-02-05  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  Issue170
	
	* artifact-database/pom.xml: Changed log4j version to 1.2.14 (later version
	  causes errors and breaks while maven build process).

2010-02-01  Tim Englich  <tim.englich@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CreateResource.java (innerPost): 
	  Put the XML-Document which was send by the client to the 
	  ArtifactDatabase.createArtifactWithFactory-Method.
	  
	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactFactory.java (createArtifact),
	  artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java (createArtifactWithFactory),
	  artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java (setup),

	  artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java (createArtifactWithFactory),
	  artifacts/src/main/java/de/intevation/artifacts/Artifact.java (setup): 
	  Changed Method signatures so that it is possible to put the Document
	  which will be send during the create Step of an Artifact to the Setup-Routine
	  of an Artifact.
	  Now it is possible to send further Informations to the Artifact using the 
	  XML-Document.
	  This is nessesary for manipoulating the Artifact e.g. setting Parameters 
	  which should only be displaied or e.g. put an Geometry-Object into the 
	  Artifact which should limit the displayed results.

	RELEASE 0.3

	* Changes, NEWS, ChangeLog: summarized activities.

2009-12-16	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/XMLUtils.java:
	  Added static method parseDocument(File) to load document from

2009-11-23	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:
	Added a context dictionary accessible through putContextValue(key, value)

	transfer information through the call level transparently.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	Adjusted default implementation of CallContext.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java:
	New. A general proxy class for artifacts in artifact databases. This class uses 
	the extended call context semantics.

	The artifact calls (feed, describe, out, ...) are passed to a proxied artifact.
	If the proxied artifact decides to be replaced by some other artifact it has to
	to store a reference to the replacement artifact in the call context with
	putContextValue(ProxyArtifact.REPLACE_PROXY, my_new_artifact). After the call
	is finished the proxied object will change. This indirect callback mechanism is
	used to minimize side effects.

	The identifier() call is not forwarded to the proxied artifact to have a stable id.

	Limitations: This mechanism does not let you build real matroska (multi level)
	like artifact structures. This would only be possible if a kind of call context
	stack is introduced.

	* src/main/resources/sql/org-h2-driver.properties: 
	Bug Fixed in SQL-Query

2009-09-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Refactored the persistent handling of the artifacts in the 
	artifact database. When an artifact is called (describe, feed,
	advance, out) a new CallContext is given instead of the
	old Object context. CallContext.globalContext() returns the
	old Object context now. CallContext.afterCall() may be
	called from inside describe, feed, advance and out to tell
	the artifact database what to do after the processing of
	the specific call.
	
	The accepted values are:
		- NOTHING    for doing nothing
		- TOUCH      for just update the last access time
		- STORE      for persisting the artifact.
		- BACKGROUND to signal that the artifact has started
		             a background operation.

	After the background operation the artifact has to call
	CallContext.fromBackground() to signal the artifact 
	database that the artifact needs to be touched or stored.

	!!! Without this call the artifact database assumes there
	!!! is still some background operation on this artifact
	!!! which prevents reclaiming resources

	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:
	New. New API to cope with background processing.

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java:
	Replaced old Object context with CallContext context.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	Adjusted.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	For a better encapsulation of the persistence operations of the
	artifacts the database does not return artifacts any more. It delegates
	the describe, feed, advance and out call to internal structures.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabaseException.java:
	New. Simplifies handling of error conditions inside of artifact database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	Adjusted to new interface. Internally it handles the background API.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactResource.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/FactoriesResource.java,

	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CreateResource.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactOutResource.java:
	Adjusted to new artifact database interface (which greatly simplifies things)

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	Artifacts in background are not removed from database any longer.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Little
	re-wirering need for new cleanup.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java: 
	Simplified to do the SQL stuff only. The most infrastructure stuff is now done
	in ArtifactDatabaseImpl.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Id.java:
	New. Helper base class to enable filtering of background artifacts by there
	database id.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	Modified the INSERT statement to write the serialized artifact, too.

2009-09-12	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java(out):
	out() is now called with an java.io.Outputstream to place
	the output.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/OutRepresentation.java:
	Adjusted.

	* artifact-database/doc/example-conf/conf.xml: Added
	sleep time for cleanup thread.

	cleanup thread to do an immediate cleanup when dead artifact
	is found by lookup.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	New. The cleanup thread. It cleans up the artifact database
	perodically and calls the endOfLife() methods of the dead
	artifacts. Default cleanup interval is 5 minutes.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	Tuned SQL a bit to fetch only a 50 artifacts in search for
	outdated artifacts to avoid too much memory consumption.

	* contrib/run.sh: Little tweak to work with more than one
	commons-pool version installed.

	* TODO: Removed remarks about the now implemented killer 
	thread and the moves XML stuff.

	* README: Changed text how to create a H2 database from
	command line only. XXX: This is still broken. The best
	way to set up the database by now is to start the Console 
	client, connect to the database, c&p the schema.sql 
	into the SQL text area and execute it.

	This is not a part of the Artifact itself because this is only evaluated once when
	the artifact is created.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	New. Simple base class implementation of the Artifact interface.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactFactory.java:
	New. Simple base class implementation of the ArtifactFactory interface. When setup()
	on instances of this class is called, it pull ttl, name, description and
	the artifact class name from the node given. See artifactdb-example-conf.xml
	for examples.

	* artifact-database/pom.xml: Cleaned up XML. 
	Introduced dependency to apache commons dbcp, used for pooling of the 
	database connections to artifact db. 
	Added parameters for the exec:exec goal to make the project
	startable without building packages.

	* artifact-database/doc/schema.sql: Removed AUTO_INCREMENT from primary key
	to avoid compatibility issues with other non-H2 databases (PostgreSQL, Oracle, ...)
	which have no or limited support for generated keys in the JDBC driver. Now
	using an explicit sequence. TTL ist now big int to bring the resolution to ms.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java:
	Refactored a bit to make the XPath access function usable on arbitrary XML
	documents and parts of.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DBConnection.java:
	New. Exposes DataSource from a apache dbcp connection pool configured by the
	global configuration file. See artifactdb-example-conf.xml for examples.
	TODO: Write some documentation about this.

	* artifact-database/doc/artifactdb-example-conf.xml: Adjusted to be a more realistic
	example config file. Added references to DefaultArtifact/DefaultArtifactFactory and
	demonstrate how to configure the connection pool.

	* TODO: Add remark to document the connection file.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:
	Do not crash when config does not contain any factories.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java (getNodeXPath):
	New method to get a single node from configuration.

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java (endOfLife):
	New method called when artifact is going to be removed from artifact data base.

	* pom.xml: Edited
	Buildplugins for Maven-Compiler and Maven-Eclipse Plugin integrated.

2009-09-04	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/doc/artifactdb-example-conf.xml: Example for artifact db
	configuration.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactContextFactory.java:
	New. Default implementation of ArtifactContextFactory. Creates a DefaultArtifactContext.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactContext.java:
	New. Default implementation of ArtifactContext.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:
	New. Class to bootstrap the context and the artifact factories.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Bootstrap
	factories.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java: New.
	Loads configuration as XML from a file. The file is specified by the system
	property "artifact.database.config" and defaults to "artifactdb-conf.xml".
	The configuration can be searched via XPath.

	* artifact-database/pom.xml: Made de.intevation.artifactdatabase.App the main
	class for start up.

	* TODO: Added remark to add logging to artifact database.

2009-09-04	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactContextFactory.java:
	New. Factory for a global context in the artifact data base. Useful to
	create shared ressources for artifacts like caches et al.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java,
	artifacts/src/main/java/de/intevation/artifacts/ArtifactFactory.java,
	artifacts/src/main/java/de/intevation/artifacts/ArtifactContextFactory.java,
	artifacts/src/main/java/de/intevation/artifacts/Artifact.java: Uses the
	global context more consistent.

	* artifact-database/doc/schema.sql: Using BINARY instead of BLOB to
	avoid external files for each artifact blob. See H2 documentation
	for details.

2009-09-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	in H2 databases.

	* artifact-database/pom.xml: Added dependencies to H2 and
	restlet.

	* pom.xml: Added repository to fetch restlet.

	* README: Describe how to create a H2 database to store artifacts.
	TODO: Make it more general because description assumes usage of
	a unixoid system.

2009-09-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/**: created new sub project for the artefact 
	database server.

	* pom.xml: Registered new sub project and made artifacts a
	sub project, too.
